摘要： Electrical energy is produced at a remote site by converting kinetic energy from the environment. The kinetic energy may include vibrations and flow of fluid. In some embodiments the kinetic energy causes magnets to move with respect to coils in order to produce electrical energy. An anchor holds the device in place, and permits the device to be retrieved or relocated. A flexure or compliant membrane that helps determine the position of the magnets with respect to coils is defined by mechanical properties that permit oscillatory movement in response to the inputted kinetic energy. The device can be tuned to different vibration and flow regimes in order to enhance energy conversion efficiency. Further, the device may be mounted in a secondary flow path such as a side package or annular tube.

摘要： Electrical energy is produced at a remote or close site by converting kinetic energy from fluid flow with membranes that generates electrical energy in response to deformation by the fluid flow passing though a piezo electric medium attached to the deforming membranes. Sets of membranes define variable fluid flow restrictors that oscillate due to interaction of the force of fluid flow and Bernoulli Effect. The device can be tuned to different flow regimes in order to enhance energy conversion efficiency. Each membrane may include one or more layers of piezoelectric material separated by insulating/stiffening layers. Further, the device may be mounted in a secondary flow path such as a side package or annular tube.

摘要： According to the invention, a method for designing a rotary drill bit for drilling a cavity in a medium is disclosed. The method may include determining a characteristic of a drillstring with which the rotary drill bit is coupled. The method may also include determining an initial number of groups of cutters for the rotary drill bit, where each group of cutters includes a plurality of cutters substantially aligned along a different radius of the drilling face. The method may moreover include determining a characteristic of the medium relative to a characteristic of the cutters. The method may additionally include determining a characteristic of a rotational motion source used to rotate the rotary drill bit. The method may further include determining the angles of pitch between each of the groups of cutters to minimize an amount of sticking or slipping of the bit in the medium during a drilling operation.

摘要： A tool generates signals indicative of shear wave slowness of the formation surrounding a borehole. The tool comprises a collar portion adapted for mounting in a drill string, a quadrupole sonic transmitter mounted to the collar portion, and a quadrupole sonic receiver array mounted to the collar spaced apart from the transmitter. A method determines shear wave slowness of the formation. The method includes propagating quadrupole wave energy into the formation and detecting quadrupole dispersive waveforms received at a second location. Formation shear wave slowness is calculated using dispersive slowness time coherence processing

摘要： A method, useful in computer-aided design, of identifying possible solutions to an over-constrained system having a collection of entities and constraints. The method represents the entities in terms of degrees of freedom and incrementally assembles the system by adding entities, satisfying constraints and reducing the degrees of freedom of the entities. For an over-constrained system, the method constructs a dependency graph of the system and identifies the set of constraints which over-constrains the system. The over-constraining set includes the constraint which initiated the over-constraint and those constraints back traced in the dependency graph from the initiating constraint. Removal of one or more constraints from the over-constraining set results in a solvable fully or under-constrained system. Intelligent selection of the removed constraint may increase computational efficiency or system stability. The method is useful in diverse constraint satisfaction problems, particularly geometric modeling problems such as describing mechanical assemblies, constraint-based sketching and design, geometric modeling for CAD, and kinematic analysis of robot and linkage mechanisms.

摘要： A method, useful in computer-aided design, for finding possible configurations of a system having a collection of geometric entities and constraints. The method represents the geometric entities in terms of degrees of freedom and systematically satisfies the constraints reducing the degrees of freedom of the geometric entities. The method uses a number of specialized routines, called plan fragments, which satisfy a particular constraint relating to a particular geometric entity. Each plan fragment changes the configuration of a geometric entity in space--i.e. the location and orientation--satisfying a constraint and reducing a degree of freedom. The series of plan fragments which reduce the degrees of freedom and satisfy the constraints comprise an assembly plan for possible configurations of the system. The method identifies overconstrained, fully constrained, and underconstrained systems to the user and assists in finding possible configurations if the constraints are changed, added, or deleted. The method is useful in solving any geometric constraint problem, such as describing mechanical assemblies constraint-based sketching and design, geometric modeling for CAD, and kinematic analysis of robots and linkage mechanisms. By reasoning symbolically about the geometry of the system, the method provides faster solutions, numerical stability, user feedback, and the ability to handle redundant constraints.

摘要： Electrical energy is produced at a remote site by converting kinetic energy from fluid flow to electrical energy using a downhole harvesting apparatus. The downhole harvesting apparatus includes a vibrating sleeve member that vibrates in response to fluid flow through a tubular housing structure. The vibration of the sleeve is used to generate electrical power. The harvesting apparatus may include features to help maintain constant fluid flow in the tubular structure. The harvesting apparatus can be tuned to different vibration and flow regimes in order to enhance energy conversion efficiency.
